1. Precautions
Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays.
1-1 Safety Precautions
1. Be sure that all of the built-in protective
devices are replaced.
2. When reinstalling the chassis and its
assemblies, be sure to restore all protective
devices, including control knobs and
compartment covers.
3. Make sure that there are no cabinet
openings through which people-particularly children--might insert fingers
and contact dangerous voltages. Such
openings include the spacing between the
picture tube and the cabinet mask,
excessively wide cabinet ventilation slots,
and improperly fitted back covers.
4. Design Alteration Warning:
Never alter or add to the mechanical or
electrical design of the unit. Example: Do
not add auxiliary audio or video connectors.
Such alterations might create a safety hazard. Also, any design changes or additions
will void the manufacturer's warranty.
5. Leakage Current Hot Check (Figure 1-1):
Warning: Do not use an isolation
transformer during this test. Use a leakage-current tester or a metering system
that complies with American National
Standards Institute (ANSI C101.1, Leakage
Current for Appliances), and Underwriters
Laboratories (UL Publication UL1410,
59.7).
With the unit completely reassembled, plug
the AC line cord directly into a 120V AC
outlet. With the unit's AC switch first in the
ON position and then OFF, measure the
current between a known earth ground
(metal water pipe, etc.) and all exposed
metal parts. Examples: Handle brackets,
metal cabinets, screwheads and control
shafts. The current measured should not
exceed 0.5 milliamp. Reverse the powerplug prongs in the AC outlet and repeat.
(Reading should
not be above
0.5mA)

6. Insulation Resistance Cold Check:
(1) With the unit's AC plug disconnected
from the AC source, connect an electrical
jumper across the two AC prongs. (2) Set
the power switch to ON. (3) Measure the
resistance between the shorted AC plug and
any exposed metallic parts. Example:
Screwheads, antenna, control shafts or
handle brackets.
If any of the exposed metallic parts has a
return path to the chassis, the measured
resistance should be between 1 and 5.2
megohms. If there is no return path, the
measured resistance should be "infinite." If
the resistance is outside these limits, a
shock hazard might exist. See Figure 1-2

Precautions
1-1 Safety Precautions (Continued)
7. Components, parts and wiring that appear
to have overheated or that are otherwise
damaged should be replaced with parts
that meet the original specifications.
Always determine the cause of damage or
overheating, and correct any potential
hazards
8. Observe the original lead dress, especially
near the following areas: Antenna
wiring, sharp edges, and especially the
AC and high voltage power supplies.
Always inspect for pinched, out-of-place,
or frayed wiring. Do not change the
spacing between components and the
printed circuit board. Check the AC
power cord for damage. Make sure that
no wires or components touch thermally
hot parts.
9. Product Safety Notice:
Some electrical and mechanical parts
have special safety-related characteristics
which might not be obvious from visual
inspection. These safety features and the
protection they give might be lost if the
replacement component differs from the
original--even if the replacement is rated
for higher voltage, wattage, etc.
10 Components that are critical for safety are
indicated in the circuit diagram by
shading,
or
. Use replacement
components that have the same ratings,
especially for flame resistance and
dielectric strength specifications. A
replacement part that does not have the
same safety characteristics as the original
might create shock, fire or other hazards.
1-2 Servicing Precautions
Warning1: First read the "Safety Precautions" section of this manual. If some unforeseen circumstance
creates a conflict between the servicing and safety precautions, always follow the safety precautions.
1. Servicing precautions are printed on the
cabinet. Follow them.
2. Always unplug the unit's AC power cord from
the AC power source before
attempting to: (a) Remove or reinstall any
component or assembly, (b) Disconnect an
electrical plug or connector, (c) Connect a
test component in parallel with an
electrolytic capacitor.
3. Some components are raised above the
printed circuit board for safety. An
insulation tube or tape is sometimes used.
The internal wiring may be clamped to
prevent contact with thermally hot
components. Reinstall all such elements to
their original position.
4. After servicing, always check that the
screws, components and wiring have been
correctly reinstalled. Make sure that the
portion around the serviced part has not
been damaged.
Samsung Electronics
5. Check the insulation between the blades of
the AC plug and accessible conductive parts
(examples: metal panels, input terminals
and earphone jacks).
6. Insulation Checking Procedure: Disconnect
the power cord from the AC source and
turn the power switch ON. Connect an
insulation resistance meter (500V) to the
blades of the AC plug.
The insulation resistance between each
blade of the AC plug and accessible
conductive parts (see above) should be
greater than 1 megohm.
7. Never defeat any of the B+ voltage
interlocks. Do not apply AC power to the
unit (or any of its assemblies) unless all
solid-state heat sinks are correctly installed.
8. Always connect a test instrument's ground
lead to the instrument chassis ground
before connecting the positive lead; always
remove the instrument's ground lead last.

Precautions
1-3 Precautions for Electrostatically Sensitive Devices (ESDs)
5. Use only a grounded-tip soldering iron
when soldering or unsoldering ESDs.
1. Some semiconductor ("solid state") devices
are easily damaged by static electricity.
Such components are called Electrostatically
Sensitive Devices (ESDs). Examples
include integrated circuits and some fieldeffect
transistors. The following techniques will
reduce the occurrence of component
damage caused by static electricity.
6. Use only an anti-static solder removal
device. Many solder removal devices are
not rated as "anti-static" (these can
accumulate sufficient electrical charge to
damage ESDs).
7. Do not remove a replacement ESD from its
protective package until you are ready to
install it. Most replacement ESDs are
packaged with leads that are electrically
shorted together by conductive foam,
aluminum foil or other conductive
materials.
2. Immediately before handling any
semiconductor components or assemblies,
drain the electrostatic charge from your
body by touching a known earth ground.
Alternatively, wear a discharging
wrist-strap device. (Be sure to remove it
prior to applying power--this is an electric
shock precaution.)
8. Immediately before removing the protective
material from the leads of a replacement
ESD, touch the protective material to the
chassis or circuit assembly into which the
device will be installed.
3. After removing an ESD-equipped assembly,
place it on a conductive surface such as
aluminum foil to prevent accumulation of
electrostatic charge.
9. Minimize body motions when handing
unpackaged replacement ESDs. Motions
such as brushing clothes together, or lifting
a foot from a carpeted floor can generate
enough static electricity to damage an ESD.
4. Do not use freon-propelled chemicals.
These can generate electrical charges that
damage ESDs.

Precautions
1-4 Special Precautions and Warning Labels for Laser Products (Continued)
1-4-1 Warnings
1. When servicing, do not approach the
LASER exit with the eye too closely. In
case it is
necessary to confirm LASER beam emission, be sure to observe from a distance of
more than 30 cm from the surface of the
objective lens on the optical pick-up block.
2. Do not attempt to handle the objective lens
when the DISC is not on the tray.
1-4-2 Laser Diode Specifications
Material: GaAs+ GaAlAs
Wavelength: 760-800 nm
Emission Duration: Continuous
1-4-3 Handling the Optical Pick-up
1. Static electricity from clothing or the body
may cause electrostatic breakdown of the
laser diode in the Optical Pickup. Follow
this procedure:
2. Place a conductive sheet on the work bench
(i.e., the black sheet used for wrapping
repair parts.) Note: The surface of the work
bench should be covered by a copper
ground plane, which is grounded.
3. The repair technician must wear a wrist
strap which is grounded to the copper
sheet.
4. To remove the Optical Pickup block:
Place the set on the conductive sheet, and
momentarily touch the conductive sheet
with both hands. (While working, do not
allow any electrostatic sources--such as
clothes--to touch the unit.)
Laser Output: 0.2 mw (measured at a
1.6 mm distance from the objective lens
surface on the optical pick-up block.)
5. Ground the "Short Terminal" (located on the
PCB, inside the Pickup Assembly) before
replacing the Pickup. This terminal should
be shorted whenever the Pickup Assembly
is lifted or moved.

1-5 Special Precautions for HDD
* HDD Data Maintenance Step
1. Since the data on the HDD is weak to mechanical shock, place the HDD in a safe
location that is free from mechanical shock once it is removed from the main unit.
2. In order to safe keep the data on the HDD, back up the data before the repair or
make sure not to place the HDD near any electrical appliance that generates a
strong magnetic field.

OGG (Ogg Vorbis)
OGG(Ogg Vorbis) is featured to have "higher compression rate than MP3', 'higher quality than
MP3', 'no limit in use, distribution and development due to open source type. The biggest feature of
Ogg Vorbis is that it has no limit in use of format itself.
The biggest feature that distinguishes Ogg Vorbis from existing music file is that it supports
VBR(Variable Bit Rate) by default.
Of course, MP3 also supports VBR format, but has effect of reducing capacity due to VBR based on
existing MP3. Ogg Vorbis file supports VBR by default and helps you enjoy high quality music
without loss due to big width of bit rate.

1-2. MP3 Overview
MP3 is one of file extension like .hwp, .wav, .txt used in computer.
Exactly, it is the abbreviation of MPEG Audio Layer-3.
Origin of MP3
MPEG is Motion Pictures Expert Group and is a standard made by experts in this area under international standard organization like ISO(International Standard Organization) and IEC(International
Electric Committee). It is technical standard of compressing and transmitting video and audio signals and recovering them again.
The first specification that MPEG made is MPEG-1 in 1988. It is the technology used to produce
video CD. MP3 means the audio compression part among specification of MPEG-1(1995). MPEG-2
is used together with MPEG-1. AAC(Advanced Audio Coding or MP4) receives attention with its
excellent digital audio and is derived from MPEG-2. MPEG-4(lastests standard on movie compression for conference communication) is being established.
MP3 is most widely used and called "MPEG Audio Layer-3", which is version up from Layer-1 and
Layer-2. In general, it is called MP3 since Layer-1 has compression rate of 1:4, Layer-2 of 1:61:8,
Layer-3 of 1:101:12.
Using MP3 technology, up to 100 songs(7 hours) can be contained in one copy of empty CD of
650MB.

MP3
MP3 is most widely used and called "MPEG Audio Layer-3", which is version up from Layer-1 and
Layer-2. In general, it is called MP3 since Layer-1 has compression rate of 1:4, Layer-2 of 1:61:8,
Layer-3 of 1:101:12.
AAC
MP3 is most widely used and called "MPEG Audio Layer-3", which is version up
from Layer-1 and Layer-2. In general, it is called MP3 since Layer-1 has
compression rate of 1:4, Layer-2 of 1:61:8, Layer-3 of 1:101:12.
WMA (Windows Media Audio)
Multimedia compression type of Microsoft. Only music data is compressed from
“WMT”. Streaming and file format also support this data. In a same quality as MP3,
it is about 1/2 size and contains Windows Media Rights Manager with copyright
protection technology. It can be played back with [Media Player] provided in
Windows98.
ATRAC3
Sound compression type of MD and latest specification of [ATRAC (Adaptive
TRansform Acoustic Coding)] developed by SONY. Has about 2 compression rate
than existing ATRAC.
Real Audio G2
Format type developed by Real Network. High quality can be obtained at low transmission speed of 16Kbps-32Kbps using [RealAUDIO G2 Music Codec] as compression type. Since streaming play in Internet radio is the main purpose, file does
not contain copyright protection technology. “Real Player G2” supports MP3 playback and “Real Juke Box” supports encoding from CD to MP3.

Tips
How MP3 can produce same quality as CD?
Ears of human can listen to signal in the range of 20Hz~20KHz. It is called "audible frequency". To
convey the audible sound in digital type CD, sampling frequency of 44.1KHz, about 2 times of audible frequency, should be used. It is the task of dividing sound signal to 44,100 pieces per second
and making the signal to digital format of 0 and 1. How delicately the sample can be expressed will
be determined by number of bit per sample. Audio CD is 16 bit. It means that 1 sample can be
expressed in 65,536(16 square of 2) stage.
When converting CD music to WAV file, the capacity is about 40MB(for 4 minutes). By converting it
to MP3, it reduces to 4MB since "loss compression", the feature of MP3, is used. Loss compression
type removes the sound beyond the range of audible frequency(20Hz~20KHz). It uses the features
that small sound cannot be heard after very strong sound. <Figure 1> is the sound wave before
loss compression. It can be regarded as the sound wave of music CD or cassette tape containing
sound people cannot listen. When it is made into MP3, it is as shown in <Fig.2>.
Volume Control
Capacity can be reduced much by adjusting the degree
of loss. However, it causes deterioration of sound quality. Music CD contains sound made with 16 bit
44.1KHz of stereo sampling. Stereo is the type of dividing the sound into left and right. CD should change
analog
sound to digital.
Digital information is cut between sections and location information is saved in each section.
"Sampling rate" is the standard of how many sub-section it will divide 1section. Divided frequency
part is called 8 bit and 16 bit. 8 bit sampling means that frequency is divided into 2 stage, that is,
sound pitch of 256 stage. 16 bit sampling divides into 65,536 sound pitch. In addition, 44.1KHz
means sampling of 44,100 times per second. To reduce the amount of information made at digital,
sampling bit number and frequency should be set low, but it will cause deterioration of sound quality. There is no difference in sound quality between MP3 and CD since encoding(converting CD
track to MP3) is done with 44.1KHz at 16 bit. Better CD sound quality cannot be obtained by lowering the sampling rate, but the capacity can be reduced.

Meaning of SecuMAX System Application
Most legal Internet MP3 service sites adopt SecuMAX and YEPP of Samsung and several companies have hardware supporting SecuMAX among MP3 players currently distributed. Then, user
needs to receive MP3 applied with SecuMAX to receive legal service. It is required to have program
that can play back MP3 applied with SecuMAX technology in MP3 player. For example, since YEPP
supports SecuMAX, it can play back, but it means that you cannot play back this at the players of
other companies that do not support SecuMAX.
At present, organization has been formed for standardization of reproduction prevention system in
foreign countries. Samsung Electronics has also participated in this standard using SecuMAX and
